Description

Technical Field

[0001] This invention relates to the field of steel rolling equipment technology, specifically to a scratch-resistant round steel cooling bed. Background Technology

[0002] The cooling bed used in the rebar rolling production line is a standard structure cooling bed because the surface quality requirements for the rebar are not very high. (See...) Figure 1 At the beginning of the steel entering the cooling bed, including the rotating roller 25 and the skirt plate 26, the steel 27 enters the cooling bed from the roller conveyor and is then completely cooled by the rotating roller 25. During the process of the steel entering the cooling bed from the roller conveyor, the skirt plate 26 of the cooling bed is in direct contact with the steel 27. Currently, according to market demand, there is a requirement to convert the rebar production line into a production line for rolling ¢25-¢110 billet steel. Because the surface quality requirements for billet steel rolling are high, surface defects such as scratches and dents are strictly prohibited. However, in the current production line, especially when the billet enters the cooling bed, the round billet is in direct contact with the skirt plate, resulting in mutual friction between the billet and the skirt plate. Figure 1 Point A is the friction point. Especially for round steel bars with a diameter of 50 mm or more, the frictional force is greater due to their weight, which inevitably leads to scratches and dents, causing significant quality problems and affecting the quality of the finished product. Therefore, there is an urgent need for a scratch-resistant round steel cooling bed to solve the above-mentioned technical problems. Summary of the Invention

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] A scratch-resistant round steel cooling bed includes a fixed skirt plate 9, a movable skirt plate 3, a lubrication structure, and a cooling structure. The fixed skirt plate 9 and the movable skirt plate 3 work together to allow the round steel to move on the cooling bed. The lubrication structure lubricates the fixed skirt plate 9 and the movable skirt plate 3, facilitating the rotation of the rollers installed on them. The cooling structure cools the round steel on the cooling bed.

[0028] The fixed skirt board 9 in this application remains in a fixed position when used on the cooling bed. The fixed skirt board 9 includes a base plate 2, with a lubricating oil channel in the middle of the base plate 2. The top of the base plate 2 is a skirt board, which is composed of support blocks 4. A fixing frame 1 is fixedly connected to the bottom of the base plate 2. Through the fixing frame 1, the fixed skirt board 9 can be fixed to the ground.

[0029] The movable skirt 3 also includes a base plate 2. The top of the base plate 2 is fixedly connected to a skirt composed of support blocks 4. The bottom of both ends of the base plate 2 are fixedly connected to hydraulic lifting rods 7. The extension and retraction of the lifting rods 7 can change the height of the movable skirt 3. When the cooling bed is in use, under the action of the lifting rods 7, the round steel can be separated from the fixed skirt 9, making it easier for the movable skirt 3 to move the round steel.

[0030] A hydraulic telescopic rod 5 is fixedly connected to the inner side of the bottom end of the lifting rod 7. The two telescopic rods 5 have the same extension and retraction amount, but when one telescopic rod 5 extends, the other telescopic rod 5 retracts. Under the action of the two telescopic rods 5, the movable skirt 3 can move horizontally.

[0031] The top of the fixed frame 1 is uniformly provided with grooves that are adapted to the movable skirt 3, and the depth of the groove is not less than the sum of the heights of the support block 4 and the base plate 2. In one embodiment of this application, the depth of the groove is the sum of the heights of the support block 4 and the base plate 2.

[0032] As described above, when the position of the round steel needs to be changed during the use of the cooling bed, the lifting rod 7 extends, separating the round steel from the fixed skirt plate 9. The telescopic rod 5 then moves the movable skirt plate 3 horizontally, and the movable skirt plate 3 moves the round steel horizontally by the length of a support block 4. The lifting rod 7 retracts, allowing the round steel to be placed on the fixed skirt plate 9, and the position of the round steel on the fixed skirt plate 9 changes. The lifting rod 7 continues to retract until the movable skirt plate 3 moves below the round steel. The telescopic rod 5 then moves the movable skirt plate 3 horizontally, allowing the movable skirt plate 3 to reset, facilitating the movement of the round steel by the movable skirt plate 3 again.

[0033] Fixed skirt plate 9 and movable skirt plate 3 are alternately arranged, and a cooling plate 6 is provided between adjacent fixed skirt plate 9 and movable skirt plate 3. Cooling holes are evenly provided on the outer surface of the cooling plate 6, and air is introduced into the inner cavity of the cooling plate 6. The air in the cooling plate 6 can be evenly sprayed onto the fixed skirt plate 9 and movable skirt plate 3 through the cooling holes, which is convenient for cooling the round steel.

[0034] The cooling bed also includes a blower 10. The air outlet of the blower 10 is connected to the inner cavity of the cooling plate 6 through a duct. The blower 10 and the cooling plate 6 form a cooling structure. Through the setting of the blower 10, the operation of the blower 10 can blow outside air into the inner cavity of the cooling plate 6 to achieve the function of cooling the round steel.

[0035] The support block 4 in this application is provided with ventilation holes evenly. The ventilation holes facilitate the airflow around the round steel and make it easy to cool the round steel by air cooling. The support block 4 has a mounting groove in the middle of both sides of the top. A roller 19 is movably connected in the inner cavity of the mounting groove. A bearing 20 is fixedly connected to the inner wall of the roller 19. A connecting plate 18 is fixedly connected to the middle of the bearing 20. The connecting plate 18 is fixedly connected to the mounting groove.

[0036] A connecting hole 23 is provided on one side of the mounting slot. The inner cavity of the connecting hole 23 is connected to the inner cavity of the base plate 2. A clamping tube 21 is fixedly connected to one side of the bottom of the inner cavity of the connecting plate 18. The clamping tube 21 is clamped to the inner cavity of the connecting hole 23. A spraying hole 22 is fixedly connected to the middle of one side of the connecting plate 18 and the two ends of the bearing 20. The balls on the bearing 20 are located within the spraying range of the spraying hole 22.

[0037] As described above, the inner cavities of the support block 4, the base plate 2, and the connecting plate 18 are in a connected state. The lubricating oil in the inner cavity of the base plate 2 can be sprayed out through the spray hole 22, and the sprayed lubricating oil is sprayed onto the balls of the bearing 20 to lubricate and cool the bearing 20, prevent the bearing 20 from seizing due to high temperature, and facilitate the use of the cooling bed.

[0038] The cooling bed also includes a lubrication structure that can supply lubricating oil to the cooling bed.

[0039] The lubrication structure includes an oil tank 11. An air compressor 15 and an oil pump 14 are fixedly connected to the top of the oil tank 11. A mixing valve 16 is fixedly connected to one side of the top of the oil tank 11. The air outlet of the air compressor 15 and the oil outlet of the oil pump 14 are respectively connected to the fluid inlet end of the mixing valve 16. The inner cavity of the base plate 2 is connected to the fluid outlet end of the mixing valve 16 through a mixing pipe 17. A sealing cover 12 is snapped onto one side of the top of the inner cavity of the oil tank 11. An air dehumidifier 13 is fixedly connected to the top of the oil tank 11. The air dehumidifier 13 is connected to the air inlet end of the air compressor 15.

[0040] An oil filter 24 is fixedly connected to the oil inlet of the oil pump 14, and an oil inlet pipe is fixedly connected to the bottom of the oil filter 24. The other end of the oil inlet pipe extends to the bottom of the inner cavity of the oil tank 11.

[0041] As can be seen from the above description, the roller 19 in this application is lubricated by oil-air lubrication. When the lubricating oil is sprayed on the bearing, compressed air is also sprayed on the bearing, so that the bearing is under positive pressure, preventing dust and other impurities from adhering to the bearing and affecting its use.

[0042] All electrical components involved in this application are prior art. Those skilled in the art understand their connection methods. With the help of those skilled in the art, all electrical components in this application and their compatible power supplies can be connected by wires. According to the actual situation, a suitable controller can be selected to meet the control requirements. For specific connections and control sequences, please refer to the description below. The electrical connection between each electrical component is completed in the order of operation. The detailed connection methods are well known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control.

[0043] In summary, (with Figure 2 (Referring to the direction shown) When using this anti-scratch round steel cooling bed, place the round steel on the skirt plate. At this time, the round steel contacts the skirt plate through roller 19. Roller 19 uses bearings 6205 and 6206, which reduces the friction between the round steel and the skirt plate, making it easier for the round steel to move back and forth on the cooling bed.

[0044] When the round steel moves left or right on the cooling bed, the lifting rod 7 extends, causing the movable skirt 3 to rise until it moves the round steel above the fixed skirt 9. At this point, one telescopic rod 5 extends while the other retracts. The combined use of the two telescopic rods 5 causes the movable skirt 3 to move in the direction of the extended telescopic rod 5. Once the movable skirt 3 is in the correct position, the lifting rod 7 retracts, causing the movable skirt 3 to move downwards. During the downward movement of the movable skirt 3, the round steel can be placed on the fixed skirt 9. After the round steel separates from the movable skirt 3, the movable skirt 3 continues to move downwards until it is below the round steel. Then, the telescopic rod 5 causes the movable skirt 3 to move in the opposite direction, resetting the movable skirt 3 so that it can move the round steel again.
